United finished the 2004–05 SPL season in 9th place with 36 points, in which an eventful final day could have relegated themselves, Livingston or Dunfermline, before eventually consigning Dundee to the drop.
A strong league finish secured United's top-flight status, with four wins from the final seven games, including victories against Rangers, Hearts and rivals Dundee.
During August, Paul Ritchie and goalkeeper Lars Hirschfeld arrived on six-month deals following releases from Walsall and Tottenham respectively.
The third derby match was drawn 2–2 with Steve Lovell's late leveller denying United three points, in a game where Nick Colgan – signed 24 hours previously – was given a debut.
February started in dismal fashion, with Colgan's second (and final) match resulting in a 7–1 defeat against Rangers in the CIS Cup semi-final.
With the match shown live on Sky Sports, it was a chance for United to gain television revenge for the Hampden horror show just three weeks previously.
Aberdeen were back at Tannadice three days later for a league match and won 2–1, starting a run of four straight defeats in March.
After Kilmarnock's 3–0 victory, United lay bottom and Ian McCall was sacked, with Assistant Gordon Chisholm handed temporary control.
Chisholm's first match was a live television affair at home to Celtic and only a Craig Bellamy hat-trick denied United a point, who equalised twice only to lose 3–2.
The cup semi-final brought cheer, as Jason Scotland's winner ensured a final appearance in May, along with European football.
Dundee's early goal against Livingston moved them out of bottom spot, only for ex-United player Craig Easton to equalise.
